角度4.0+；弹簧靴&x2B；Spring安全性：TemplateInputException:解析模板时出错；“登录”；

我正在我的第一个Angular项目中集成Spring Security。我遵循了许多文章和示例，包括、、和。我希望我的应用程序具有spring安全性，并通过LDAP进行身份验证。如果我将login.html保存在\src\main\resources\templates中，则可以看到登录页面。但是我希望登录页面来自Angular组件。因此，我从\src\main\resources\templates中删除/重命名了login.html。当我点击localhost:8080时，它会转到我的LoginController（yu=ou可以在日志中看到sysout），然后我会看到下面的错误

在谷歌搜索之后，我尝试了很多方法，但都没有成功。有什么建议吗

我的文件：

LoginController.java

 @RequestMapping("/login")
    String login(){
        System.out.println(">>>>>>>>>>>> LoginController.login()...");
        return "login";
    }

WebSecurityConfiguration.java

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
        //.httpBasic().and()
        .authorizeRequests()
      //  .antMatchers("/**").permitAll()
        .antMatchers("/index.html", "/", "/home", "/login").permitAll()
            .anyRequest().authenticated()
            .and().formLogin().loginPage("/login")
            .and()
        .csrf()
            .csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse());
        /*http
                .authorizeRequests()
                .antMatchers(HttpMethod.GET, "/resources/**", "/assets/**", "/css/**", "/js/**", "/fonts/**")
              //.antMatchers("/**")
                .permitAll()
                .and()
                .authorizeRequests()
                .anyRequest()
                .authenticated()
                .and()
                .formLogin()
                .loginPage("/login")
                .successHandler(authenticationSuccessHandler)
                .permitAll()
                .and()
                .logout()
                .logoutUrl("/logout")
                .and()
                .csrf()
                .csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse())
                .and()
                .httpBasic();
                //http.cors();
*/    }

app-routing.module.ts

const routes: Routes = [
    { path: 'login', component: LoginComponent },    
    { path: '', redirectTo: '/home', pathMatch: 'full' },
    { path: 'dashboard', redirectTo: '/home', pathMatch: 'full' },
    {
        path: 'home',
        component: DashboardComponent,
        data: { title: 'Dashboard' }
    },
    {
        path: 'linesidemonitor',
        component: LinesideMonitorComponent,
        data: {title: 'Lineside Monitor'}
    },

如果使用.and（）.formLogin（），则会出现以下错误：

2018-04-28 08:32:08.394 DEBUG 10404 --- [nio-8080-exec-6] o.s.s.w.a.ExceptionTranslationFilter     : Access is denied (user is anonymous); redirecting to authentication entry point

如果我使用.httpBasic（）和（），那么我将得到我不想要的浏览器登录弹出窗口

@SK

出现以下异常的原因是您使用的是控制器，而不是RestController

org.thymeleaf.exceptions.TemplateInputException:解析模板“登录”时出错，模板可能不存在，或者任何已配置的模板解析程序都无法访问模板 位于org.thymeleaf.TemplateRepository.getTemplate（TemplateRepository.java:246） 位于org.thymeleaf.TemplateEngine.process（TemplateEngine.java:1104）

因此，它不是直接将输出作为JSON写入浏览器，而是使用ViewResolver来解析MVC的视图部分

用RestController替换Controller将使

.formLogin（）.login页面（“/login”）

使用login发出浏览器请求，并且在允许的情况下，您将获得登录页面

httpBasic，这是浏览器弹出窗口的本质，因为它会得到401响应代码。

我改变了方法。我再也没有了。所以我们无法测试这一点。但是非常感谢你花时间回答这个问题。我真的很感谢你的努力。你有什么样的申请表吗？如果是，请分享（可能是github链接）
